LYING AND SECURING RAILS IN ROAD-BEDS OF RAILWAY'S.

SPECIFICATION forming part of Letters Patent No. 299,208, dated May 2'7,1884i.

Application filed December 17, 1883. (No model.)

.T @ZZ whom, t iii/ty concern:

Be it known that I, .IEANTY DNCHAUD, Sr., of the city and county of SanFrancisco, and State of California, have invented an Improvement inLaying and Securing Rails in Road-Beds of Railways; and I hereby declarethe following to be a f'ull, clear, and exact description thereof.

- now in existence, but is more especially adapted to be used inconnection with my safety railwaycar heretofore patented by me, and inwhich rollers secured by arms tothe car are adaptedto be projected intothe groove of the rails to prevent derailment.

In any road a great object to be gained is to prevent the rails fromspreading. If this can be done, many accident-s will be averted; butwhen the rails are to be used with my safety-car it is of primeimportance that they shall be strong enough and laid firmly enough toresist the strain of the projected rollers, and to remain accurately inplace without spreading, so that the rollers may always find theirbearing when projected.

Referring to the accompanying drawings, Figure lis a plan of my rail,showing the clamps for securing them in position. Fig. 2 is a verticalcross-section of same, showing the manner of laying them. Fig. 3 is aplan of a slight ly-modified rail and means for clamping. Fig. i is across-section of same. Fig. 5 is a crosssection of a rail resembling thecommon form now in use, but with my flange formed with it, and showinghow it is laid.

A is the rail. This is formed in a T shape, with an outer and innergroove, the rolling surface being preferably flat. It has formed with iton its outer side an upwardly-extend` ing flange, a, andadownwardlyextending fiange, a. In laying the rail its base is iinbeddedin the cross-tie B, and its lower flange, a', extends well down into thetie.

C is the brace or clamp. This is of an L shape, and consists of a bodyof about an equal height with the back of the rail, and anoutwardlyextending flange, c. formed a curvilinear bulging lug, d,preferably hollow for the sake of lightness. This clamp is also embeddedin the cross-tie, and fits its curved lug d into the outer groove of therail. Bolts e pass through the clamp and rail, one at the top throughthe upper flange of the rail, and one at the center through the lug. Thehead of this latter bolt is to be countersunk, as shown, to preserve asmooth surface on the inner groove, to adapt it for use in connectionwith my safety railway-car. A spike, b, is driven through the flange cof the clamp into the cross-tie. At the joint of two rails the clamp Cis made sufficiently long to brace both rails.

By embedding both rails and clamps in the ties, great stability is giventhem, andby clamping them together thus securely they are notliable tospread, but will remain firm and even. The embedded flange of the railof itself gives great firmness. This rail, it will be seen, can bereversed.

A modification of this rail, made for the sake of economy and topreserve the style now in use as nearly as possible, is shown in Figs. 3and 4. I-Iere the upper flange, a., is omitted, the rail being providedwith a lower flange only, which, together with the base of the rail, isembedded, as in the first rail, in the crossties. The top of the rail isof the common shape, and the clamp is made to conform to the modifiedrail by reducing the height of its body. It is secured to the rail by asingle central bolt; but in case it should be found impraeticabletochange entirely the present system of rails and means for securing them,I show in Fig. 5 but a slight change from the present rail. This has theaddition of the iiange a embedded in the tie, as is also the base of therail. The ordinary spikes secure it to the cross-ties, and thefish-plates are here shown as lying on the inside, to keep the outergroove smooth in case it should be desired to use the rail in connectionwith any safety-car On its face is IOO having rollers adapted to t theouter groove.

The clamps or braces shown may be made of Wood as well as iron, thusmaking them moreeconomical and equally as strong.

This improvement'in laying and securing the rails Will give a greateconomy in crossties, because they may be put at Wider distances andstill give solidity to the rails, as the latter are embedded in them.

I am aware that prior to my application railroad-rails constructed withiianges adapted to fit grooves formed in the cross-ties had been made,and such I do not claim; but

What I dol claim, and desire to secure by Letters Patent, is-

l. In the road-bed of a railway having crossties B, the rail A, having aflange, a', the base .of said rail and its ange being embedded in thecrossltie, in combination with the L-shaped brace or clamp O, having acurvilinear or bulging face, d, fitting the outer groove of the rail,said clamp being bolted to the. rail7 and having its base embedded inthe cross-tie and spiked thereto, substantially as herein described.

2. In the road bed of a railway having cross ties B, the rail A, havingthe lateral flanges a a", and side grooves, in combination with theL-shaped clamp or brace having a curvilinear or bulging lug d on itsface, tting the outer groove of the rail; anda means forsecuring theclamp to the rail and the rail and clamp to the cross-tie, substantiallyas herein described. p

In Witness whereof I have hereunto set my hand.
